CompareDiff
Compare text, JSON, images, and PDFs locally in your browser, free, private, no signup.
A local-first diffing toolkit covering text, JSON, images, and PDFs in one place. Nothing uploads to a server, so it's a reasonable fit for comparing sensitive files without leaving your browser.
What we like
- Text, JSON, image, and PDF comparison in a single browser toolkit
- Fully local processing, files never leave your device
- No account or install required
- Line, word, and character-level text diff modes
- Image diff and a before/after slider included
What to watch
- No real-time team collaboration or cloud-synced comparison history
- No API for batch processing
- File size caps apply, images up to 5MB and PDFs up to 25MB
